Go with the 1.60
I have a YS120 in mine now and and have a 1.60 in a SIG Cap 231... It weighs around 14 lbs and has unlimited vertical...
I've made up my mind from all I've read here to pull the YS120 and put in the 1.60... The 1.20 did not have unlimited at all..
What a sweet plane overall tho... My fav bigger plane so far...
We'll see how that stands after an AW 33% Edge 540T and my "getting there" Mile's Reed Weeks Solution XX...
